Abstract

Current harmonic filter is a unit connected in parallel with the load at the load itself which injects the total harmonic current demanded by the load, and thus preventing harmonic current going into the power system. This paper describes the basic design, control modeling and simulation of a single phase current harmonic filter. Modeling and simulation is done in the MATLAB SEVIULINK environment. The filter consists of a current source inverter (CSI) with a front end fixed rectifier to obtain required dc voltage. This filter can eliminate harmonics up to about 50^th order. Analog closed loop scheme is used to control the inverter. Basic simulation of the harmonic current filter, the control system and simulation results are discussed in the paper.
